I am repowering with a 2004 Mercury EFI 225 from a 1989 Johnson OMC.

I have rewired and am now addressing the tachometer.

It has a 1 - 6 selector.

I have order the 5 pin harness.

I have included some photos of this tach.

Does anyone know if it will work?

If so, what would be the setting 1,2,3,4,5 or 6?

Please advise?

Re: Mercury Tach/OMC Question

The setting will be the same as the Johnson. Both have 12 pole alternators.
